This part of IEC 60684 gives the requirements for two types of heat-shrinkable, polyolefin sleeving, dual wall, not flame retarded with a nominal shrink ratio of 3:1.<\/p>\n
This sleeving has been found suitable for use at temperatures of up to 100 \u00b0C.<\/p>\n
These sleevings are normally supplied in colour black.<\/p>\n
Since these types of sleevings cover a significantly large range of sizes and wall thicknesses, Tables A.1 and A.2 provide a guide to the range of sizes available. The actual size shall be agreed between the user and supplier.<\/p>\n
Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.<\/p>\n
